What are the reasons for a car not accelerating when pressing the gas pedal?

[VonWalter]

The reasons for a car not accelerating when pressing the gas pedal include: 1. Clutch slipping: The symptom of clutch slipping is that when you press the gas pedal hard, the engine speed increases quickly, but the vehicle speed does not rise accordingly, resulting in a noticeable lack of acceleration. You can try replacing the clutch plate. 2. Poor fuel quality: Using low-quality fuel can affect the gasoline filter and fuel lines, potentially causing poor fuel supply and resulting in weak acceleration. 3. Throttle body carbon buildup: Carbon deposits accumulating in the throttle body can affect the air intake volume, leading to insufficient engine power and the car not accelerating when pressing the gas pedal. You can clean the throttle body.
